HEEL-BREASTING MACHINE.

Application filed November 8, 1911.

To all "who m itmag concern Be it known that I, RALPH C. Snurons, acitizen of the United States, residing at Beverly, in the county ofEssex and State of Massachusetts, have invented certain Improvements inHeel-Breasting Machines, of which the following description, inconnection with the accompanying drawings, is a specification, likereference characters on the drawings indicating like parts in theseveral figures.

This invention relates to shoe machinery and is of particular utilitywhen embodied in a machine for performing upon shoes the operation ofheel breasting, although I contemplate the use of my improvements forany purpose to which they are adapted.

An important feature of my invention is the provision of a machine ofthis class having a plurality of power operated devices arranged to bepresented respectively, for actuation at different times, to treat thework, which is preferably presented sub stantially in the same operatingposition, regardless of the device selected for any given operation.

Another important feature of my invention is the provision ofpositioning and clamping devices in a series corresponding to theaforesaid power operated devices, to serve respectively as guides andabutments, each preliminary to, and during, action by the appropriateoperating device, the series of operated devices being respectivelymovable, independently of each other, to their relative positions forcooperation upon the work.

A. very important feature of my invention is the provision of a seriesof breasting knives, and their appropriate abutment guides, so that theymay be instantaneously presented in operative position by a simpleturning movement, without preliminary adjustments, for breasting theheels of either right or left shoes.

Another feature of importance is the provision, as part of the sameseries, of a breasting knife, and its corresponding abutment guide whichhas a contour differing from others in the series.

Ofsimilar importance also is the feature of my invention comprisingmeans for effecting the substitution of a fresh knife for one which mayhave become worn, injured,

or out of adjustment, leaving the replacing or readjusting of the knivesthus disqualified to be effected at a time when the machine is at rest,or when it will not be disadvantageous to interfere with its operation.

A further feature of my invention is the provision of means for thesuccessive treatment of the work by operating devices acting to performtheir work progressively, as for example a simple curved breasting knifesucceeded by a scalloping knife, and the breasting device may besucceeded by the action of a member arranged to print the manufacturersname or trade-mark upon a selected portion of the heel or shank. Thisseries of operating devices may be assembled in compact arrangement upona turret, (which term I use as designating any r0- tatable supportwithout further limitation,) and this turret may be adapted to existingmachines of this type. The abutment guides are preferably assembled insimilar relation for their convenient adaptation to, and actuation inconnection with, the cooperating parts of well-known heel breastingmachines.

Further means is provided also for the rapid adjustment of the aforesaidturrets by hand into their various positions, and means for locking themfirmly at their several points of operation also for swinging theturrets temporarily out of their operative planes to permit adjustivemovements of the turrets themselves and to clear the work and operativeparts of the machine for access at times.

Accordingly, in carrying the invention into effect a support in the formof a turret is provided which is rotatable in a vertical plane andcarries the operating devices. For this purpose the turret is mountedupon a horizontal stud projecting from and reciprocable up and down withthe front slide, for example, of a heel breasting machine, and I havedevised a special form of stop or bunter, one for each of the operatingdevices in the series, these serving interchangeably in cooperation withthe means which disengages the usual connection pivoted at the rear ofthe front slide. This connection is normally interposed between theknife slide and the rear or actuating slide which is connected with thepitman of the machine, so that when the pitman is reciprocated thebreasting knife normally is operated to a point where further movementwould cut the shank, and then the bunter or stop touches the shank,knocks the strut out from under the roller on the. rear slide, therebydisconnecting the knife slide from its actuating, slide so that furtherdownward movement of the pitman and rear slide is not communicated tothe breasting knife, but the latter is raised by the rear slide intoposition for another breasting stroke. By my improvements one strut andpush rod serve for engagement with a series of shipper levers mounted onthe turret, one lever for, and coiiperating with, each of the breastingknives.

' The various featuresofmy invention will be illustrated and describedfully in the accompanying drawings and specification and pointed out inthe claims.

In. the drawings,Figure 1 is a view in front elevation of a power heelbreasting machine in the construction of which my improvements have beenembodied, parts being broken away toreveal more clearly the structure ofother parts; Fig. 2 is a view in right side elevation of the head ofsaid machine, on an enlarged scale; andFig. 3 is a view in horizontalsection on the line, 3-3, Fig. 1, looking in the direction of thearrows.

In the embodiment of my invention illustrated,.the part designated bythe reference numeral 1 is the support for my improved mechanism,taking; the form in the instance illustrated of a metal column, thelower part of which carries the usual power shaft 2 with fly wheel 3connected intermittently by a Horton clutch 41 which is controlled by afoot lever 5, serving to actuate intermittently a verticallyreciprocating pitman 6 connected by a pin 7 with a rear slide 8 movablevertically in guideways formedkin the frame. At 10v 1 have shown a frontslide, Fig. 3, mounted in the same ways and having a stop 13 to permitupward movement of the slide 10 by the slide 8. Aspring 15 (see Fig, 1)tends normally to raise the front slide 10 toward its uppermostposition, being connected to an arm 17 bolted at 19 to the front slide10,

The above mentioned parts may be, and preferably are, as usual inmachines of this type and it will su'liiceto state that when the footlever 5v is depressed the Horton clutch connects the constantly rotatingfly wheel 3 with the shaft 2 which hasa crank 12 pinned tothe pitman 6,and the. latter is recipro cated, the pitman moving the slide 8 up anddown. Then a bow spring let entering the path of a shoulder-16. on. theHorton 0111130114 throws the latter offandzpermits the fly wheel to berotated freely by power.

A brake 18 operated by a spring 20 against aneocentric 22v checks, theshaft 2- and crank 12 with the pitman 6 and rear slide 8 at their highpoint, all this being as usual, and springs24-and' 2,6 serverespectively. to hold the foot lever 5 and clutch controllingmember 28intheirnormal inoperative positions illustrated in Fig. 1. Otherwell-known parts include the support '30 for; the shoe comprising aswinging post mounted pivotally on the frame 1 at 32, and carrying anthese knives to be presented in position to breast the heel of a shoemounted' on the toeand heel supporting members38 and 40 off the acln Asone convenient form of device to accompli'sh the above presentation, aturret 48 is shown mounted rotatably about a horizontal. stud 50 formedupon the front slide 10, a cap plate 52.f'astenedby screws 54 serving-toprevent axial displacement of' the turret, which is shown as triangularin fi'ont elevation as there are three knives 42, 44

and 46.

In Fig. 1 the knife 42 is shown in itsvertical operative position, and adescription of its mode of support by the turret will suffice to conveya proper understanding of how each of the knives is supported, thesupporting means being preferably of identical construction so that theknives will be interchangeable. The shank 4:3 of the knife 42 extendsupward between bridge blocks 56, 58, and set screws pass through eachfront bridge block into engagement with the knife shanks and serve toclamp the latter and prevent lateral displacement of the knives. Byloosening the screws 60 engaged with either of the knives 4:2, 44 or 46,the knife may be adjusted relatively to the turret, and when the knifeis worn and ground away so that it is desirable to setthe bridge blocks56 and 58 nearer the working edge of the knife a firm grip may still beretained on the shank. The bridge blocks are movably mounted in throatpieces 62, forming part of the structure of the turret 48.

Suitable means may be provided to hold the knives to their work, such asthe abutment screws 64 secured against rotation by set screws 66,supported in a portion 68 of the turret which lies between the portions7 0,, 72, Fig. 2. The face 72 is shown as provided with three aperturedlugs 74, each fitted to receive an indexing bolt 76 when in registrytherewith, to hold the turret steady with one of the knives in operativeposition, as for example, the knife 42 shown in Fig. 1. This bolt 76,shown clearly in Fig. 2, is carried by a lug 78 on the head of place forsuch cooperation.

the front slide 10 and is provided with an operating handle 80.

In Fig. 2 may be seen also at 82 one of the detector and shipper devicesutilized in this type of machine to engage the shank of the shoe andtrip the connection between the knife or front slide 10 and theactuating or rear slide 8. Three of these devices are provided, one foreach knifejand I have devised a novel arrangement by which thesedetectors cooperate interchangeably with the shipper mechanism, beingmoved auto matically by rotation of the turret into The construction ofthese detectors may correspond with that of the well-known type and asillus trated each comprises a two-arm lever 84, 86 mounted on arock-shaft 88 having bearing lugs 90 on the turret 48. The lever arm 84carries the detector member proper 82 which is manually adjustable bymeans of the worm 92 into position to touch the shank of the shoe in thedescent of the turret 48, while the other arm 86 of the lever ispresented in position to push rearwardly a'strut 94 mounted pivotally at96 upon the front slide 10, and having a heel 98 engaged with a spring100 which normally tends to throw the heel 98 outward and thereby tohold in the position shown in 2 the strut proper 94, whose function isto afford means by which the rear slide 8 is connected at times with thefront slide 10 to operate the slide carrying the turret 48 and theknives, such actuation being effectedby engagement of the strut 94 witha roller 106 pivoted in the rear slide 8. This roller permits the strutto be pushed out easily, even when under considerable pressure by reasonof the down ward'thrust of the slide 8 under the action of the pitman 6,and those skilled in the art will understand readily that thisunshipping action supervenes when the detector 82 strikes the shank ofthe shoe as the knife 42 reaches the end of the breasting stroke, thedetector rotating upon the shaft 88, pushing the strut 94 outward toclear the roller 106, and permitting the slide 10 with turret 48 andknives 44, 44 and 46 to stop in their downward movement and to be subsequently lifted to normal inoperative position by action of the spring15, in conjunction with the lifting action of the rear slide as it comesin contact with the plate 13 upon its return stroke.

In accordance with my invention I prefer to interpose an independentconnecting member 108, such as the push pin illustrated in Fig. 2,between the lever finger 86 and the strut 94, in order to permit freeradjustment of the two part detector lever 84, 86, suita le means beingprovided for such adjustments, as for example by providing a set screw83, with lock nut 85, carried by the lever 84 as shown in Fig. 2, thepoint of the screw bearing against a shoulder 89 of the lug 90, so thatthe lever arm 84 is held normally in the rotative position shown in Fig.2, even when the rotation of the turret moves the finger 86 away fromits po sition of cooperation with the push pin 108.

In accordance with another valuable feature of my invention, I provide aseries of clamping and guiding devices, one corresponding to each of theoperating devices in order that the workman may have an accurate guideto assist him in placing the heel of the shoe for treatment, andclamping the same in position and each of these abutment guides may takethe form of such a plate as is usually provided in machines of thischaracter, and the operation of which is well understood by thoseskilled in the art. In the drawings 1 have shown three of these presserguide plates, 110, 112 and 114, of which the plate 110 is in positionfor use relatively to the knife 42, and has a contour corresponding withthat of the knife, their cotiperation being sufficiently clear when itis stated that the shoe having been placed heel upward upon the pin 40the top of the heel is engaged with the plate 110 and located relativelthereto so that the guiding edge of the plate will be exactly in theposition where it is desired that the breasting cut of the knife 42should take place. I prefer to provide for movement of these abutment'uide plates 110, 112, 114 so that each one mav be brought readily asneeded into the position occupied by the plate 110 for the breastingoperation just described. This may be provided for by any suitablestructure, and as one convenient form of such device I have shown aturret 116 similar in general arrangement to the turret 48 alreadydescribed, this turret being supported by a vertical post 1 8 carried bya bracket 120 pivoted on and extending laterally from a slide 122mounted to reciprocate vertically in guideways 124 formed in an arm 126bolted at 128 upon frame 1 of the machine. The slide 122 is connectedfor actuation with a lever 123 mounted pivotally at 125 upon a bracket126 on the machine frame and having a pivotal connection 130 with avertically movable rod 132, preferably of the type usually provided forthe actuation of presser guide plates in machines of this character; theslide 122, arm 126, lever 123 and operating rod 132 being preferably ofthe type well-known to those skilled in the art.

Adjusting means, such as the lock nut 134 (see Fig. 2) and the coilspring 136 with thumb nut 138 to regulate the tension of the spring areusual eXpedients for the purpose indicated, as is also the thumb nut 140and clamp 141 to hold the sleeve 142 in place relatively to the lever123.

The presser guide plates 110, 112 and 114: may be of any suitablematerial and contour, and may be mounted in any suitable fashion uponthe turret 116 and as one convenient construction I have shown plates ofthe character usually provided in heel breasting machines, but differingfrom each other in contour, the plates 112 and 114; being reverselycurved for treatment of right and left heels ofthe same pair while theplate 110 exhibits a different curve. The plate 114 also is shownasprovided with marking devices 113.

It is desirable to mount each of the plates 110, 112 and 11a forlongitudinal adjustment and I have accordingly shown each of the platesas slotted at 117, Fig. 3, to receive each a bolt secured to a backplate 152 and having a wing nut 156, Fig. 2. The forward part of theplate 152 is provided with an undercut groove 151 to receive the head ofa stud 150 secured to the back of each of the presser guide plates 110,112, 114:, this arrangement permitting the plates to be moved backwardand forward longitudinally in a horizontal plane relatively to the heelpost 10 of the shoe support when the wing nuts 156 are loosened. Setscrews 158 having check nuts 160 are carried by a support 159 formed onthe turret 116 and are provided to engage the rearward projection 115 ofthe back plates 152 respectively to regulate the angular relation ofplates 110, 112 and 114 respectively relatively to the horizontal, inorder to provide for adjustment to the 7 plane of the top of the heelwhen the latter departs from the horizontal. For this purpose the backplates may be tilted around 7 horizontal rock shafts 162 passing throughthe plates into lugs 161 carried by the turret 116. Springs 220 areprovided to hold the plate normally in contact with the adjusting screws158.

Inasmuch as the plates 110, 112 and 11 1 are usually of such length thatthe frame 1 would interfere with their swinging movement in a horizontalplane, I have provided for a tilting movement of the entire turretbodily with the plates and for this purpose the bracket 120, to whichthe turret is pivoted, is pivotally supported by a shaft 168 in a head170 carried by the vertical slide 122, and as one convenient form ofdevice to operate the turret to tilt the same I have shown a handle rod17 2 movable rotatively in a bearing 17% carried by the bracket 120,

the forward end of the rod 172 being fluted as at 176 to engage rackteeth formed upon an indexing pin 178 movable vertically in the member170 to enter each of the series ofholes 180 in the turret 116, this pinserving to hold the turret in fixed position with the plate llOor plate112 or plate 114: in poapplied upwardly to the plate which is inoperative position. This handle rod 172 may be provided with a coilspring 182 engaged with a pin 184 in the member 170 and a pin 186 in asuitable collar 188 upon the handle rod 172, so that when the handle rod172 is released the coil spring 182 tends normally to throw the indexpin 178 downward into engagement with the turret 116. V

In order to change the position of the plates 110, 112 and 11 1, theoperator grasps the handle rod 172, twists the same around itslongitudinal axis to clear the pin 178 from that one of the holes 180 inwhich it may be placed at the time, and then the operator, still holdingthe handle 172, uses it to swing the turret 116 bodily with the platesaround the shaft 168, and then the turret 116 can be grasped by theoperator and turned with the post 118, the plates swinging clear offrame 1 until the selected plate is in practically the position of theplate 110 as shown in the drawings, and then the turret 116 is swungbodily by means of the handle 172 back to its horizontal position, the

handle is released, and the operator by mov dependently of the positionof the actuating lever 123 and its related parts, permitting the releaseof the plate from engagement with the shoe so that the shoe can be withdrawn or adjusted to the knife.

Accordingly, in the operation of my improved turret power heel breastingmachine,

' the parts being in the position illustrated in Fig. 1, the shoe isplaced upon the last pin 40 and toe rest 38, the hand wheel 36 is turnedto operate the extension rod 34: and bring the shoe into approximatelyits proper position for treatment, adjacent to the guide and abutmentplate 110, which is first turned into position as just described, andthe turret 418 having been turned about its stud 50 to bring intoposition the selected knife 42, the latter will be held in place byautomatic entry of the index bolt 76 within the proper apertured lug 74.The operator then depresses the treadle '5 in the usual manner, therebycausing plunger 132 to draw down the lever 123 and slide 122, moving theturret 116 downward into its position where the plate 110 engages theheel of the shoe, and further movement of the foot lever 5 throws in theHorton clutch 4 in well-known fashion and the pitman 6 is operated bycrank 12 to draw down the rear slide 8 and the front slide 10, throughcontact of the roll 106 with the strut 94, the front slide 10 carryingwith it the knife 42 to'breast the heel. At the end of this breastingstroke the detector 82 strikes the shank of the shoe, is rocked on shaft88 to bring its finger 86 against the push pin 108 to force the strut 94from under the roll 106 and thus release the knife, slide 10 andoperating turret 48 from the actuating slide 8, permitting them to stoptheir downward movement and await the upward movement of slide 8, whichupon coming in contact with the plate or stop 13 raises the slide 10aided by spring 15. The turret 116 also is raised by the upward movementof plunger132 under the action of spring 24: when treadle 5 is released,and the appara tus is now ready for another operation which may be arepetition of that already described or any of the operating devices andcoiiperating presser guide plates may be brought into play bymanipulation of their respective turrets in the manner hereinbeforedescribed.
